Is This Earthquake Dangerous?
A magnitude 4.1 event is classified as a light earthquake. Noticeable shaking of indoor objects and rattling doors/windows. Generally causes none to slight non-structural damage in older buildings.
Estimated Shaking Across Nearby Communities
Felt by almost no one except under extraordinarily favorable conditions.

What Does Magnitude 4.1 Mean?
Earthquake strength is measured on a logarithmic scale. Compare this event with the full seismic scale:

Because seismic scales are logarithmic, each whole integer increase represents:
Why Did This Earthquake Happen?
This event occurred along the Peru-Chile (Andean) Subduction Zone, where the dense oceanic Nazca Plate slides eastward and plunges underneath the continental South American Plate at roughly 6 to 8 centimeters per year. This megathrust boundary is one of the most seismically active fault zones on Earth.
Originating at a depth of 124.0 km (Upper Mantle / Wadati-Benioff Zone (70–300 km)), this rupture occurred originated within the descending oceanic plate inside the upper mantle. shaking radiates over a wider geographic area with attenuated high frequencies.
Aftershock Outlook & Secondary Tremors
Seismologists note that minor aftershocks remain common in the 24 to 48 hours following tremors of magnitude 4.1. According to statistical seismic models, there is roughly a 5% probability of a subsequent event of equal or greater strength occurring in the same fault zone. Residents in Peru are advised to check living spaces for unsecured items.

Earthquake Safety Action Plan
Complete Safety Guide →- •Drop, Cover, and Hold On: Take cover beneath a sturdy table or desk.
- •Stay indoors away from exterior glass windows and heavy unanchored fixtures.
- •If outdoors, move into an open area away from power lines and building facades.
- •Inspect utilities for damaged gas lines, water leaks, or electrical hazards.
- •Expect Aftershocks: Secondary tremors frequently strike after significant events.
- •Avoid damaged structures and listen to official emergency broadcasts.
- •Maintain a 72-hour emergency go-bag with water, food, and first aid.
- •Anchor heavy furniture, water heaters, and appliances to structural studs.
- •Establish a family emergency communication protocol and meeting point.
Frequently Asked Questions
Common questions and answers about this earthquake.
No. No tsunami warning, watch, or advisory was issued by the Pacific Tsunami Warning Center (PTWC) or the USGS for this M4.1 event. The focal depth (124.0 km) and magnitude did not generate sufficient vertical seafloor displacement to trigger a hazardous tsunami wave.
